The vet took one look at kitty and pronounced she was dying. He recommended she be euthanized. Daughter-in-law said no way. It was not the first time I'd seen this happen with her.
The vet made his decision with his brain. He had no emotional involvement with the cat. He's a trained clinician and could see it was dying. He saw euthanasia as the most responsible option.
Daughter-in-law was all heart, and emotion. She was not open to vet's logical thinking.
I says to myself "Self, we've got a problem." I whipped out my phone and called son at work. He talked to both of them.
Final decision was to do nothing at that moment. The kitty has a very old chip. Son will decide tonight whether to euthanize the cat and pay the bill, or attempt to contact owner. Highly likely owner information has never been updated.
Daughter-in-law needed some time for her heart to say good-by to kitty. Vet thought death was eminent. She may well decide to let kitty die at home while she lovingly cares for it.
Everyone has their own opinion of what's appropriate. I would have chosen immediate euthanasia but I would not force that on her.
In the past when one of their cats is dying they keep it at home. After it dies Son takes it in to be cremated. She will set up a small shrine with a candle, and whatever else is appropriate, perhaps a picture, maybe the ashes, I don't recall. I think this may go back to the Shinto religious tradition. Heck, I don't know, it just may be unique to her.
Bottom line, we took the kitty back home. It's now up to Son to sort it all out tonight.
